The Impact Related Stories One of the main goals of the upcoming Electron-Ion Collider (EIC) is to uncover the origin of proton spin. The EIC will measure the transverse motion of quarks and ...

Artist’s depiction of a proton’s interior. In quantum chromodynamics, the constituent quarks come in three “colors,” along with up and down “flavors.” Also shown are virtual quark ...

Nuclear scientists used a new theoretical approach to calculate a value essential for unraveling the three-dimensional motion of quarks within a proton ... force governed quark-gluon interactions.

Beta (\(\beta^-\)) decay is the release of an electron by the change of a neutron to a proton. The neutron (charge = 0) is made up of one up quark (charge = \(\frac{2}{3}\)) and two down quarks ...

Dragging two up quarks and one down quark from the dispenser to the Nucleon Assembly area, which sits near the center of the window, forms a proton. Dragging one up quark and two down quarks to ...

Beta decay involves the conversion of a down quark to an up quark. This changes a neutron into a proton plus an electron. The proton stays in the nucleus and the electron leaves the atom with high ...

In this work, nuclear physicists and particle physicists collaborated to develop a novel framework that consistently describes both the particle (quark-gluon) and nuclear (proton-neutron ...

Jets are created when a quark or gluon within a proton or neutron in one of RHIC's ion beams collides intensely with a quark or gluon in the nuclear particles that make up the beam traveling in ...
